Abstract
Abstract A system that displays text and graphic information with vertical blanking interval of a publicly broadcasted video signal. The system also includes a personal computer that has a VBI decoder which can separate the data from the video signal. The separated data contains command and address information, which instruct the personal computer to retrieve text/graphic information from a storage device, and display the retrieved text/graphic information on a computer monitor. The personal computer also contains a NTSC decoder which can decode the video signal and display a television image on the computer monitor. The broadcaster inserts data that retrieves text and graphic information which correspond to the television image displayed by the computer monitor. The retrieved text and graphic information may be stored for later viewing by the user.
